MEANS FOR EXTRACTING CRUDE SPIRITS AND ROSIN FROM YELLOW AND GREEN PINE STUMPS.

Application filed January 10, 1921. Serial No. 436,202.

and useful Improvements in Means for lCx-' tracting Crude Spirits and Rosin from Yellow and Green line Stumps, of which the following is a specification, reference being had to the accompanying drawings.

'This invention relates to means for extracting crude spirits and rosin from yellow pine stumps, dead pine, green pine shucks or tops, lumber trimmings, and green yellow pine stnmps, slabs, and other; ordinarily waste mill products, and particularly to an extractor in the nature of a retort wherein the wood is subjected to a dry distillation for the purpose of extracting the crude turpentine and rosin from the wood.

The general object of my invention is to provide an extractor of this character which is particularly adapted and particularly" designed for extracting crude spirits and rosin from timber which is ordinarily wasted, such as stumps, tops and fragments of pine lumber which accumulate around saw mills.

A. further object is to provide a device of this character wherein the retort is heated by steam.

Another object is toprovide an extractor of this character formed of a central retort and a water and steam jacket exterior to the retort, the enclosed space being adapted to be filled with steam or to be partially filled with water from which steam may be generated. P

And a further object inthis connection is to prove the space between the outer and inner walls with a unitary furnace designed to heat the water within this jacket, the furnace having the usual grate 'and smoke stack but not coming in contact with the innor wall enclosing the Wood being treated but being entirely separated therefrom so that the wood will not be burned.

Another object is to provide a retort of this character wherein the floor or bottom of the retort is so formed as to support the wood to be treated and to permit the more or less fluid material extracted from the timber to be thrown off and carried to asuitable receptacle, the retort being so formed that the lower end of the retort may be detached to permit the dumping of the Specification of Letters Patent.

residue from which the crude spirits and rosin have been secured.

'Uther objects relate to the details of construction and arrangement of parts as will appear more fully hereinafter.

My invention is illustrated in the accompanying drawings, wherein Figure l is a vertical sectional view through a turpentine extractor constructed 111 accordance with my invention;

Figure 2 is a section on the line 22 of Figure 1; I

Referring to these drawings, it will be seen that the. extractor consists of a body having an outside wall ll) and an inside wall 11, these walls being separated from each other and the inside wall, illustrated in Figure 2, being disposed eccentrically to the outside wall. The inside wall is preferably copper-lined. The space. between the outside and inside walls at its narrowest part is about three inches, while at its widest it is about eighteen inches. The inside wall extends down below the outside wall and the upper ends of the outside and inside walls are connected by means of an annular sheet or plate 12 riveted or otherwise attached to the. inner and outer walls. -The lower end of the space 1 between the walls is closed by a like annular plate 14 riveted or otherwise secured to the inner and outer walls, the inner wall 11 extending down below this plate 14. lhus there is provided a water and steam space 13 extending approximately from the bottom to the top of the retort. The top of the chamber 15 enclosed by the wall 11 and forming the retort proper is closed by a cap or cover 1 6 which, when closed. rests upon a flange or other suitable supporting means disposed below the upper end of the wall 11. The top cap 16 is copper lined and is, generally speaking, conical in form and is formed with a marginal, outwardly projecting flange which rests upon the supporting flange of the wall 11 and this flange 17 of the cap is disposed sufliciently below the upper end of the wall 11 that clay or other luting material may be tamped around the joint. Preferably a safety valve 18 is connected to the steam space 13.

Extending up through the space 13 at the widest part of this space is the flue 19. this fine extending downward to any desired distance and opening into a fare pot 20 having i a grate 21. This fire pot and grate may be of any suitable construction, and preferably the fire box is provided with a doorQl. The flue and the fire pot are entirely surrounded by the water space 13 so that the heat of the flue and the fire pot will be communicated to the water and steam will be generated within the space 13. It will be understood that the upper portion of the space 13 will be filled with steam, while the lower. portion of the space will be filled with water. This water may be forced into the lower portion of the space 13 by any suitable means. I have illustrated for this purpose the injector 22 of conventional form operated by steam led to the injector through the pipe 23 which extends to the upper portion of the space 13. The injector is.

' of course, connected, as by a pipe 2 1, to any suitable source of water. Any other means may be used, however, for forcing water into the space 13 against the pressure of steam therein. A suitable water gauge 25 will be connected to the lower portion of the space 13 to indicate the height of water within this space.

The lower end portion of the wall 11 is provided with lugs 26 upon which rests a perforated plate 27. The wood which is disposed within the retort chamber 15 rests upon this perforated plate. The plate .is held to the lugs by means of bolts 28. Forming the bottom of the retort space 15 is the bottom cap 29 which is somewhat conical in form, generally speaking, and fits upon the outslde of the downwardly projecting. portron of the wall 11. It is provided with lugs 30 through which bolts 31 depending from the plate 14 pass. Nuts on the bolts 31 hold this bottom cap in place. The bottom cap is approximately three feet four nches in diameter. The cap is-in the form of an inverted cone and at its lower end the cap terminates in an angular bend or extension 32 which is'tap ered to fit within a pipe section 33, in turn leading to a pipe section 34 passing through a cooler or condenser 35 WhlCh is filled with water for the purpose of condensing the crude spirits as they are discharged from the lower end of the base cap 29. i

The retort is charged by removing the top cap and filling the retort chamber 15 with sticks or timber resting upon the perforated plate 27. After the turpentine has been'exacted by means of the steam heat, this'cap is removed. The nuts on bolts '28 are removed and the perforated plate-27 drops down. As illustrated in Figure 1, this extractor is supported between three feet and four inches above the ground or floor, thus giving ample room for the discharge of the timber after it has been treated and the turpentine, rosin, etc., extracted. The sup ports may be p rm n n as for instance in a mill, or they may be part of a wagon frame or truck frame upon which this extractor may be mounted. In either case, these supports engage the plates 14 so that the base cap may be readily removed and the wood within the retort chamber be removed after it has been treated. I have illustrated thisbe utilized, and where this extractor is designed to be used in the woods, the tops and stumps of yellow or fat pine can be worked up along with the dead and slashed wood. When the extractor is used in a mill,

steam may be admitted to the space 13from the mill boiler, but for use in the woods, the extractor will be preferably mounted on a truck and thus made portable, as stated. A gang of extractors may be used, only one of which may have a furnance for generating steam, the other extractors of the gang being connected to the first extractor to take steam therefrom. Whenever the material round about the extractor for a certain radius has been used up, the extractor may be moved to a new positionand other waste timber may be treated to sweat the crude turpentine therefrom. Of course, it will be understood thatthe crude turpentine spirits are to be distilled in the usual turpentine still.

It will be noted that with my extractor the furnace is separated at all times from the wall of the retort chamber 15 so-that the wood is not burned, which injures the spirits extracted, but the retort is practically entirely surrounded by steam and is entirely heated by steam, though the steam does not come in-contact with the wood itself. I have found that by this manner of treating the timber it is possible to secure turpentine from waste pieces of wood, slashings, dead wood, and the like, and that a large amount of turpentine can be relatlvely cheaply secured from tracts of timber where the turpentine has been extracted in the usual fashion, and which tracts would be otherwise practically valueless.

While I have illustrated a form of my invention which I have found to be entirely practical, I do not wish to be limited to this, as it is obvious that many changes might be made in the details of construction and arrangement of parts without de- -1. An extractor for sweating crude turpentine from wood comprising a body having an outer and inner wall to provide a steam and water space entirely surrounding the inner wall. the upper and lower ends of the steam and water space being closed, the inner wall defining a retort chamber having a uniform diameter from end to end, the space between the inner and outer walls constituting a steam chamber, a removable cap mounted upon the upper end of the inner wall and having a diameter approximately equal to that of the retort chamber, said inner wall projecting below the bottom of the steam and water space, a bottom cap fitting this projecting portion of the inner wall and detachably engaged therewith and having a duct whereby the crude spirits may be withdrawn, and a perforated plate detachably engaged with the inner wall and extending across the retort space above the bottom cap and supporting the wood to be distilled within said retort chamber.

52. An extractor for sweating crude turpentine from wood comprising a body having an outer and inner wall to provide a steam and water space entirely surrounding the inner wall, the inner wall enclosing a retort chamber, a fire box forming part of the body and partially enclosed by the water space and having a flue extending upward through the water space, a removable cover for the retort chamber, means within the retort chamber for supporting wood therein but permitting the drainage of the extracted turpentine, and a bottom for the retort chamber having a fluid duct leading therefrom.

3. An extractor for sweating crude turpentine from wood comprising a body formed to provide an outer wall and an inner wall, the inner wall being eccentric to the-outer wall and extending below the outer wall,

able conical-shaped base cap fitting over the inner wall but removable therefrom, the

lower contracted end of the base cap having an a'ngularly contracted portion formed with a discharge duct, and a perforated plate removably disposed within the retort chamber above the base cap.

In testimony whereof I hereunto afix my signature.
